I Patented May 28,1912.

To all whom it may concern Be it known that I, GEORGE W. COLLIN, a citizen of the United States, and resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certainnew and useful Improvements in Flusher-Valves,' of which the following is a specification.

This invention relates to a'simple form of flushing valve for use upon water closets,

. wash bowls, and similar places for drawing -desiredquant-ities of water, and whereby "the flow of water will be automatically'cut ofl when the valve handle. is released by the attendant.

It is the pur ose of my device to provide,

a praotical'an inexpensive form of valve that is adapted to be used as a closet flusher when connected intermediate 'of a closet bowl and the service pipe, or WhlCh may be produced in the'form of a. basin cock for supplying water-to a wash basin, or in fact one which may be employed in numerous other places where it may be desired to manna ly'draw quantities of water' and'liave; the same shut .ofl automatically when the valve isreleaSed; to accomplish'the above; results withoutthe use of springs or-packings, which elements'frequently wear out and cause trouble, and finally to design the valve in such a way that the same can readily be disassembled for cleaning or repairs;

With the above and other minor objects; in view my invention resides and consists in the novel construction and arrangement -o'f parts shown upon the acco'mpanyin two sheets-of drawings forming a part 0 this specification, upon which similar characters of reference denote like or corresponding parts throughout the several figures and of which;

Figure 1, shows a central vertical lon tudinal section of my improved flusher v-a ve, oom lete, and in a closed position. .Fig. [2,

45 is a so a central vertical longitudinal tion but taken at a rightangle to Fig. 1. --Fi 3, is a lan view of the valve shown in igs.. 1 an 2. Fig. 4, is a detached plan 'view of the handle used on the valve. Fig. 5, is a plan view of a modified form of my invention carried out in the form of a'basin cock, and Fig. 6, is a central vertical longitudinal section of the basin oock'shownin 5, and more clearly showing the application of my invention. a

Commercially speaking the two forms of my invention are called by different trade names since in design they have been shaped to better meet the. uses to which they areput, yet in construction they difi'er principally in the shape of the casing and the relative location of the water inlet and outlet.

Fi s. 1 to l' inclusiveof the drawing show the o-rm of my invention to be used as a closet flusher and referring thereto in detail 10 indicates th'e'casing which is formed of one iece being cored, bored and finished, to pr uce the several compartments, -passages, inlet and outlet. The casing is further provided with a threaded hub '11 for attachment to a water service pipe, and

through which'hub an inlet 12 is formed to admit the water throu h the valve. 13 represents the piston c amber, and. 14 a screw plug in upper end for inclosing the chamber in" a manner to allow the removal of the piston 15 mountedtherein. The-piston carries a stem 16 to which the'main valve '17 is secured, the same being provided with-guide'ribs-18 that engage the sides of the lower port 19 leading from the said-piston chamber. The upper inner edge of the port 19 is beveled as shown to snugly re-' ceive the under beveled side of the valve 17.- Beneath the said ort 19 and valve'I'? as shown may be the central portion". of the inner Through the inlet 12 is a vertically disposed.

end 0 rib 21 that is arranged parallel with the piston stern, which I will term a splitter since it serves'todivide and distribute the waterevenly againstthe face of the piston valve and all sides of the stem. The 'cy-lin- 5 dricalinlet12 is provided with an annular groove 22 which is covered. by a cylindrical screen 23, which serves to prevent dirt from entering'theby pass and getting-under the valves, andl' is ofsuch a shape asto be cleaned with each direct flow of water therethrough. Leading from the said groove 22 is a by pass 24 having a beveled valve seat 25 therein adapted to receive the tapered end of a needle valve 26 for regulating the amount of water to pass throughsaid valve and adjustably mounted in sleeve '27 threadably secured in the casing, the bypass 24 has its outlet into the upper portion of the piston chamber, above the iston, andserves to admit water thereinto rain theinlet to establish and maintain a pressure upon the top of piston in a manner to hold the valve 17 down upon its seat, to prevent any leakage of water through the port 19.

the free end of the r be used for a flusher.

A port 28 leads from the upper portion of the piston chamber, and communicates with the outlet 20 and is provided with a valve seat 29. A bore 30 is arranged to intersect this port as shown, and comprises a large upper portion and a smaller lower portion forming an annular seat 31 therein. A plug valve 32 is slidably mounted to snugly fit both of said bores and is rovided with finished shoulders to engage 0th the seats 29 and 31, the former to control the flow of water from the piston chamber and the latter to prevent any leakage of water therefrom. This plug is provided with a series of annular grooves 33 in its periphery to form water packings to prevent the water from leaking up around the plug and as a provision for such leakage as may get past said grooves, I provide a drain in the plug which comprises lateral holes 34 that extend in from the periphery of the plug to take any water thaltmay get past the lower water packing grooves, which holes intersect a central longitudinal hole 35' that has its outlet at the lower end of plug and into the open end of port 28 and to the outlet. The plug 32 is further provided with a reduced neck 36 in its upper portion to form shoulders intermediate of which are seated the two members of the divided end 37 of an operating lever 38 fulcrumed to a pin 39 secured to the-casing. The weight of this lever upon the plug causes it to normally rest in a closed position as seen in Fig. 1, but the plug may be manually raised and the lower valve 29 o ned by lifting up andle as will be obvious and in a manner that will insure said parts again dropping to their lowered position, when released. From the foregoing it will be seen that by reason of the divided end 37 of the handle 38 straddling the reduced cylindrical neck "portionof the plug the latter may readily be turned with a suitable screw driver in a manner to grind or regrind both of the valves to their seats 29 and 31 without disconnecting any of the parts.

Referring to Figs. 5 and 6, it will be seen that it is only necessary to change the shape and proportions of a few of the parts in order to adapt m invention to use as a basin cock the caslng 40 of which is of a somewhat difierent design than what would water faucet. The combined length of the piston and valve is much shorter in this form than when used in the -flusher valve 'port, a differential area The valve for the shown upon the other sheet. This form of valve is furthermore simplified somewhat though otherwise isssubstantially like the only be necessary to raise the outer end of the operating lever 38, which in turn raises the plug 32 from the seat 29 to allow an escape of water from the upper chamber of casing through the port 28, which action releases the pressure upon top sides of-piston thus causing the pressure beneath to raise said piston and its valve, opening the main passage through the. valve and allowing a direct flow of water through the screen and port 19. The instant the handle is released and allowed to drop, the plug valve again closes the port leading from the upper chamber causing the main water pressure to again build upthrough the by-pass 24 before mentioned.

Having thus described my invention what I claim and desire to secure by Letters 1. The combination of a casing having an I inlbt and an outletcommunicatln through a port, a valve for opening and c osing the iston connected with the valve for actuating, the same, a cylinder within the casing in which the piston reciprocates, an inlet passage through which liquid passes from the inlet to the cylinder to exert a greater pressure on the side of the piston 0 larger area than does the inlet pressure exert on the side of smaller area to normally hold the valve seated, a drain passage leading from the cylinder to permit liquid to flow out of the latter faster than it enters through the inlet passage whereb the inlet pressure acting on the side of t e piston of smaller area handle forms the sole retaining means therefor, said, shoulders permitting the valve to be turned for grindin its seating portion.

2. In a device of t eclass described, the

combination of a casing having a drain passage, a vertical chamber communicating with the passage, a seat at the juncture of the chamber and passage, a plug valve fitting slidably and movable vertically in the chamber and normally engagingthe seat by gravity, said valve having circumferential liquid packing grooves and a conduit for conduct-mg 01f liquid escaping past the grooves, spaced shoulders on the valve, and

an operating handle having one end extend-,

ing lnto an pivoted in the casingand di'sposed between the shoulders of the valve whereby the handle normally retains the valve in place and seated.
